(Observed in Arizona) Code talker - Wikipedia " The term Code Talker was originally coined by the United States Marine Corps and used to identify individuals who completed the special training required to qualify as Code Talkers with their service records indicating "642 – Code Talker" as a duty assignment. Today, the term Code Talker is still strongly associated with the bilingual Navajo speakers trained in the Navajo Code during World War II by the US Marine Corps to serve in all six divisions of the Corps and the Marine Raiders of the Pacific theater. However, the use of Native American communicators pre-dates WWII. Early pioneers of Native American based communications used by the US Military include the Cherokee, Choctaw and Lakota peoples during World War I.[3] Today the term Code Talker includes military personnel from all Native American communities who have contributed their language skills in service to the United States. Other Native American communicators—now referred to as code talkers—were deployed by the United States Army during World War II, including Lakota,[4] Meskwaki, Mohawk,[5][6] Comanche, Tlingit,[7] Hopi,[8] Cree, and Crow soldiers; they served in the Pacific, North African, and European theaters.[9]"
On 22 August 1942, the United States Army Corps Head Quarters and the Canadian Military Head Quarters (CMHQ) began recruiting Cree speakers, already stationed in England, to use the Cree language to disguise Allied communications.
